Post-quantum authentication to origins is now supported

Cloudflare's Authenticated Origin Pulls and Custom Origin Trust Store now support post-quantum authentication. Here we’ll explain how you can configure fully post-quantum secure mutually authenticated TLS connections to your origin server, dive into the engineering details of how we built it, make a shameful confession, and finally explain how this work fits into our overall post-quantum migration roadmap.

Best Atlassian Apps to Reduce Cloud Costs

Are you trying to reduce Atlassian Cloud costs? Runaway software expenses are usually driven by three specific factors: dormant user licenses, slow manual provisioning, and paying for full access seats for temporary external collaborators. To optimize Atlassian Cloud costs, you need to address these root cost drivers directly rather than paying for seats nobody uses.

Falcon Cloud Security July 2026 Release: Helping Security Teams Move Faster in the Cloud

Every change in a cloud environment creates new security decisions. A new infrastructure as code (IaC) template needs to be validated. Cloud permissions need to be reviewed. An application release introduces new cloud interactions. A Kubernetes cluster needs protection before it goes into production. Individually, these are routine tasks. Together, they create growing operational friction that makes cloud security harder to scale.

Natural disasters and government interference: examining Q2 2026's major Internet disruption events

Like most infrastructure, the Internet's fragility is easy to overlook — as long as it's working. When it fails, its complexity comes into full view. Cloudflare is in a unique position to detect and document the moments when one of the interrelated systems the Internet depends on breaks down and connectivity suffers as a result. Each quarter, we summarize the disruptions we detect and annotate on Cloudflare Radar.

LimaCharlie Cloud Security: CNAPP Walkthrough

A walkthrough of Cloud Security in LimaCharlie — CNAPP capability built into the SecOps Cloud Platform. Connect your cloud and SaaS providers (AWS, GCP, Azure, Okta, Google Workspace, GitHub, Cloudflare, Anthropic, and even other LimaCharlie orgs) and everything is normalized into a single security graph: identities, permissions, workloads, and data. The engine reasons over that graph to surface attack paths — evidence-backed chains an attacker could actually walk — instead of isolated checkbox findings.

We're open-sourcing our privacy proxy CLI

Debugging privacy-preserving protocols is hard. Oblivious HTTP has several different steps across four different parties, not to mention binary HTTP encoding and details spread across many draft RFCs. We've taken what we've learned operating protocols like Oblivious HTTP at the scale of millions of requests per second, and wrapped it up in a nice, clean CLI tool — that we are open-sourcing today. We call it our privacy-client, or pvcli.

Best Cloud Penetration Testing Providers in 2026

Most cloud breaches begin with a configuration error the customer made. Gartner projected that through 2025, 99% of cloud security failures would be the customer’s responsibility, caused by misconfigured identity and access management, exposed storage, and over-permissioned services. Cloud penetration testing is the simulation of real-world attacks against cloud infrastructure on AWS, Azure, and GCP to find those exploitable gaps before an attacker does.

BGP ORIGIN attribute manipulation and its impact on the Internet

Border Gateway Protocol (BGP) is the de facto routing protocol of the Internet. It offers built-in mechanisms to allow entities, represented by Autonomous Systems (ASes), to express how they want to send and receive traffic on the Internet. One such mechanism is path attributes, which carry essential routing information and metadata for their associated route.
